Has anyone done this....

I took the Color Basic Unraveled Series (Color Basic so far) and text grabbed
the source code to a text (.asm) file. I brought it into the Dunfield assembler
and after some cleanup and error correction I no have a fully sourced CoCo O.S.
ready for modification.

Why did I do this? Why does anyone climb a mountain? Because it's there! LOL

Anyway, I haven't ran it on a CoCo yet but I see no reason to think it shouldn't
run.

I plan on doing the ECB and DECB also. If anyone wants a copy, let me know.
